Running Linuxcnc inside virtual machine article

Just came across this:

docs.google.com/file/d/0B6HTUUWSPdd-Zl93MVhlMnRJRjg/edit

Apparently they are running some RT linux inside a virtual machine running on a separate core and getting very good latency's.
Would this be an idea to get Linuxcnc running on modern hardware?

The link does not display anything for me.

Would this be an idea to get Linuxcnc running on modern hardware?

Linuxcnc does run on modern hardware, if the hardware is low latency. The problem is that the manufacturers of motherboards in particular, have no interest in supporting realtime computing.
This is why older machines often out perform new ones.

The next release of Linuxcnc will run on ARM as well as PC type processors and run with rtai, rt-preempt and xenomai. It does so now, its just that the development is not completed to the release stage yet.

Virtual machines are for people who are so wedded to another operating system that they just cannot stand to leave it, even to run something on a different system.
They add a huge level of complexity to something that could be very simple.

It's an interesting concept, in the 'to see if it can be done' category but I'm not sure if it lights a way forward.

It looks at present as if the future may be more in embedded boards, possibly ARM based, in controllers and remotely accessed from other computers.
That way the board can do the low level stuff and the remote computer does the graphical rendering etc where low latency is not an issue but higher processing power can be utilised.

But that could have changed by next year
